Wireless mesh networking: theories, protocols, and systems
IEEE Wireless Communications, 2006ireless mesh networking has become an indispensable technique for next-generation wireless networks. It is a critical solution to deploying large-scale wireless networks without relying on preexisting infrastructure. It also enables quick and easy extension of local area networks into a wide area.

On a Theory of Mesh-Refinement Processes
SIAM Journal on Numerical Analysis, 1980A general theory of mesh-refinement processes is developed. The fundamental structure is a locally finite, rooted tree with nodes representing the subdivision cells. The possible meshes then constitute a distributive lattice. Under mild conditions on the given cell-size and error-indicator functions a local Pareto-type optimality property is introduced

Meshing Theory of New Epicycloids Gear Drive
Advanced Materials Research, 2011In order to realize the pure rolling, improve the contact ratio, remove the backlash and raise the life, a new epicycloids gear drive is put forward. The drive part of the particular mechanism is a wheel with the roller tooth and is called the roller gear. And the driven part is the epicycloids gear.

Meshing Theory of ZC1 Worm Drive
Volume 10: 2019 International Power Transmission and Gearing Conference, 2019Abstract The toroidal enveloping cylindrical worm drive, also called the ZC1 worm drive, is grinded by the toroidal grinding wheel. In this paper, the meshing theory for this worm drive is systematically established. According to this meshing theory, the meshing function, the meshing limit function, the equations of the worm helicoid and

MESH INDEPENDENT CELL MODELS FOR CONTINUUM DAMAGE THEORY
Fatigue & Fracture of Engineering Materials & Structures, 1994Abstract— The conventional use of continuum ductile damage mechanics in finite element analyses identifies the “cell” in which damage occurs with the finite elements in which the distribution of stress and strain is modelled. Since the cell size is a fixed, metallurgically‐defined, property of the material being analysed, this methodology forces a ...

Parameterization of mesh-models
Proceedings of the 2006 ACM symposium on Solid and physical modeling, 2006Mesh parameterization has been a very active research topic for the last several years, since it appeared as a fundamental tool for a wide class of problems in Digital Geometry. Its applications include texture mapping, geometry processing, remeshing, pasting, morphing, compression and reconstruction to name but a few. Computing a parameterization of a

A mesh generation method based on set theory
Computers & Structures, 1973Abstract A method is proposed to study automatic generation of input data to finite element programs by the computer with minimal human involvement. Based on a set of objective criteria, a consistent procedure is developed to scan through the geometric idealization of a boundary to form regions for mesh generation.

Mesh generation and mesh adaptivity : theory and techniques
2018In this chapter we are concerned with mesh generation methods and mesh adaptivity issues. Nowadays, many techniques are available to complete meshes of arbitrary domains for computational purposes. Planar, surface and volume meshing have been automated to a large extent. Over the last few years, meshing activities have focused on adaptive schemes where

Contemporary Compatibilism: Mesh Theories and Reasons-Responsive Theories
2012AbstractThis article considers two of the most widely discussed types of new compatibilist theories under the headings of “mesh theories” and “reasons-responsive theories.” The first part of the article examines hierarchical theories, focusing initially on Frankfurt's theory, which is the most widely discussed of such theories. It considers three kinds
